<P>PROBLEM TO BE SOLVED: To know the detail of abnormality in case that abnormality occurs in the phase control of a motor. <P>SOLUTION: This motor controller 100a is equipped with a motor 1 which is equipped with an outer peripheral side rotor and an inner peripheral side rotor capable of changing each other's relative phase, a phase changing means which has a hydraulic controller 13 that controls hydraulic pressure, according to an energization command concerned with a relative phase, and a failure deciding control unit 67 which acquires a real phase value concerned with the relative phase and also decides the existence of the abnormality of the hydraulic controller 13, based on the difference between the target phase value concerned with the relative phase geared to the energization command and the real phase value. <P>COPYRIGHT: (C)2009,JPO&INPIT |
